Application med March l, 1922. Serial No. 540,273.

'lhis invention reletes to improvements in the construction ot templejoints or ophthalmic mountings7 ond hes 'lor its object to provide :ionepiece temple joint member comprising u. spur member herring' e,berbed shenlt adapted to be torced into :i nonnietnsllc mu.- teriel undhaving n peir oit specedepert pivot bearing eers formed integral withits outer end thus providing e. one-piece metal temple joint memberwhich is extremely strong end dursble in construction end which wheninserted into position mey be so imbedded into the non-metellic portionoit' the mountingu es to be invisible when the temple members ere swung'to open or operutive position.

llith these und other objects in view9 the invention consists ofcertoin'novel tentures 'ot construction, es will be more :tully -dcjscribed, zindpnrticulerly pointed outin the tltl dll

oppended claims..

ln the ecconipenyinp; drawings:

llipgure Q issn enlerged view ot my improved temple joint showing thenonmetzillic stoclr oit the temple into which the spur portion ot thejoint is imbedded.

Figure 3 is s top view ot my improved joint pertielly in'section showingthe spur es imbedded into the temple.

Figure 5 is e perspective view showing the two nrieinbersol.2 the jointinterlocking one with the other.

With vreference to the drawings, l0 designetes the usuel spectacle framewhich is termed either wholly or in port ot non-motellic 'motorini suchlor instance es Celluloid, raylonite or other suiteble meteriulsind tothe outer ends of this freine member ere hinged the temple members., themole member l2 ot the joint being' provided with e. curved shrink i3preferebly berbed es et ll to be inserted or imbedded into the endmember ot the treme, end which is grooved to receive it es shown inFigure 1, is adapted to be enjoint geged by the female member of thewhich letter member is provided with e peir of spaced-apart pivot eers.

ln some instances in the old style treme the lemele portion ot the jointis termed by slotting the end ot the non-1netullic temple to lorm orecess tor the reception ot the mele portion ot' the joint-ond in someother ceses these non-metallic joint eers on either side ot the slot oreprovided with metollic bushings, but in both ot' these ceses thesenon-inetullio pivot'eers ere not sulliciently stron@ to' withstand theusuel twisting stroins enr ottenbreelr. ln some ceses seperote metellicttl eer members ere inserted into the ends ot 'these non-metallictemples which lieve not proven entirely sotisl'uctory.

lily improved construction c-ontempletes the termin@` ot the lemolemember ot the joint complete und entirely ot one pieceoil: metel endproviding the some with e spur lli prelierebly berbed in stegpgeredreletion. on sevj A.erel ot its tierces es et l@ end adopted to beinserted into the end et o. non-motellic temple ll. 'lhe outer end otthis spur is provided 'with e. peir ol specednpert joint eers lil, oneet which is drilled es ltr while the opposite eer is drilled end topp-edes et 20' to receive between them the usuel pivot screw 21"; oleo inorder to stiften the joint when the two members thereolB ere connectedtogether l here linished the inner surtece lll between thetwo eers l@ onthe erc ol e circle to lit the corren spondingly hnished surtece 22 elthe mele member thereby increesing1 the beuring suru luce ot the twomembers rendering the joint very strong, stid und dureble to stondeirces sive streins which it muy be subjected to.

ltly improved one-piece motel temple joint is extremely strong unddureble lin construe tion, is simple end precticel to munutecture und bycoopereting with the mele port-ion ot the joint provides e veryrigidjoint which will withstand the excessive strains which ere brought tobeer upon the seme. 'llhis onepiece temnle joint member by being' formedentirely ont motel muy be mede ver smell und well edoptedto be deeplyimbeddled into the end of the temple member end practically covered endinclosed by the non-metallic portion oit the temple so thet the moteljoint will lbe practically invisible when the temple is swung to open oroperative position.

The foregoing desori tion is directed solely l towards the constructionillustrated, but I lill lill

lllli desire it to be understood that the shank 15 with its femalebearing member which enters the temple and the shank 13 with its malebearing member which enters the end piece4 metallic material and havinga pair of spacedapart pivot bearingears formed integral with its outerend to receive the male member between them, the stock jolmng saidbearing ears being formed on the concave are of a clr'- cle to serve asa continuous bearing seat for the abutting outer surface of said malemember, in all of its different positions.

2. A metal temple joint member for nonmetallic spectacles comprising aspur member having more than two faces and pointed at one end to beforced into the non-metallic end of the temple, barbs on more than twoof the faces to assist in holding the spur in the temple, and a pivotbearing on the outer end of said spur..

3. A metal temple joint member for nonmetallic spectacles comprising aspur member having a lurality of faces and pointed at one end to eforced into the non-metallic end of the temple, barbs on more than twoof the faces of said spur to assist in holding the spur in theI temple,said barbs being arranged in staggered re ation, and a pivot bearing onthe outer e'nd of said spur.

4. A metal temple joint member for nonmetallie spectacles com rising aspur member having a plurality o faces and pointed at one end to beforced into the non-metallic endy of the temple, barbs on each of thefaces of said spur to assist in holding the spur in the temple, saidbarbs on adjacent faces being arranged i n staggered relation, and apivot bearing on the outer end of said spur.

In testimony whereof I aix my signature.
